This makes it sound like the compressor in a turbocharger.Compressor mah! The more rpm means more air con gas is circulated hence the air con is cooler.......lol
Fan is okay. Blowing. Gas pressure din't check.bro renesis, aircond condenser fan OK ? check gas pressure too.
If thermostat jammed like my previous case, then really hard to detect until it is too late.Many new makes do not have the water temp meter dy. blue then warm up disappear, by the time red color appears may be too late.....lol
